What is the “double trust” (the tragedy of macbeth, act i, scene vii, line 12) that macbeth would be breaking if he kills duncan?

King Duncan trusts Macbeth. King Duncan trusts Macbeth to protect him because he his is subject, and Macbeth believes that he should protect him for being kinsman. He also considers himself the King's host, meaning he should be trying to get people that try to kill the King away, not actually "bear[ing] the knife [him]self", or being the one to murder him. Macbeth believes that the King is a good one, someone who is humble and virtuous. For these reasons, Macbeth does not want to kill him and to do so would gibe Macbeth a lot of guilt.
